And despite the winning run, Pearce doesn't believe Arsenal been that impressive.
It was also their seventh consecutive league victory and moved them up to fourth place, two points behind leaders Manchester City.
While it was announced that Chilwell had extended his current contract with Leicester until 2024 over the weekend, he is one of several players who have been posited as the answer to Arsenal's left-back conundrum in the press. It is a very big match and very important for our confidence.
'Mesut is a player that always keeps giving his best and is always surprising everyone and he's a player that we're very grateful and very lucky to have. "This feeling together is very good".
Leicester came within inches of retaking the lead as Leno charged off his line but got nowhere near James Maddison's corner, which Ndini thundered against the crossbar.
Arsenal, who came into the match having scored 14 of their 19 league goals in the second half, were a different proposition after the break.
Ozil appeared to embrace the role as the World Cup victor led by example to help Arsenal to bounce back from an early own goal to ease to a resounding 3-1 victory. In this moment we are two teams both in first position. Falling behind to Leicester City, it fell to Mesut Ozil, the team's captain for the night, to dig them out of a hole. We had the opportunity to score goals, we looked very risky going forward.
Now, the club has released the team news ahead of the clash but it doesn't make for good reading, the Gunners could have a crisis at left back.
The Arsenal playmaker equalised for his side shortly before half-time against Leicester City at home on Monday with a fine first-time strike.
And Ozil's 30th Premier League goal moves him clear as the top German goalscorer in the Premier League, while he has scored three goals in his last four league appearances.
The second saw him calmly lift the ball over Kasper Schmeichel to Aubameyang to finish in an empty net for his second goal in as many minutes.
